<c:if> no <c:else> can replace structure with <c:choose>:   <c:choose>         <c:when test= "" >     if       </c: when>            <c:otherwise>   otherwise        </c:otherwise>   </c:choose>      at the same   In <c:choose> , when all  <c:when>  conditions are not established, the main content of  <c:otherwise>  is executed.       Syntax       <c:otherwise>      main content    　　   </c:otherwise>      Properties       no       Restrictions      ·<c:otherwise>  must be between  <c:choose>  and  </c:choose>      ,<c:otherwise>  must be the last label when in the same  <c:choose>        Description       in the same  <c:choose> , if all  <c:when>  When the test property is not true, the  <c:otherwise>  ontology content is executed.       Example       I give a typical  <c:choose>, <c:when> and <c:o therwise> example:      <c:choose>      <c:when test= "${ Condition1} ">      condition1 for true      </c:when>      <c:when test= "${ condition2}"
